Notes on restricting private messages

Disabling private messages will cause sending a private message to
throw an error; the Zulip UI will appear to still allow private
messages. We expect to make some UI adjustments when private messages
are disabled during the beta period.

Even if private messages are disabled, users can still exchange
direct private messages with bot users (this detail is important for
Zulip's new user onboarding experience). Consider also restricting
bot creation when using this feature.
